Im having trouble with the keyboard on the Macbook Pro 2017 Retina, 4 Thunderbolt ports, with touchbar. The Command key, seems like it is broken. The top of the key is attached, but it seems like the bottom part of the Command key are sitting loose. I can lift it up. When i try to look, it seems like the attatched part is broken. Does anyone had the same problem? What will it cost to fix it, since it looks like something has broken in the attatched part on th key
